1. How to prepare compound for LSR liquid silcione drop molding?
For drop casting production, LSR (Liquid Silicone Rubber) is adopted. LSR A/B base compound, silicone thinner, silicone pigment paste and platinum curing agent are proportioned, mixed uniformly at low speed and vacuum defoamed to get bubble-free compound for subsequent dispensing and drop molding.
2. How to compound HTV solid silcione for compression molding?
HTV / HCR (High Temperature Vulcanized Rubber, VMQ raw gum) is used for compression molding. Raw gum is blended with fumed silica, color masterbatch and structure control agent via open mill mixing. Peroxide curing agent is added at low temperature for refining, sheeting and seasoning; cut rubber blanks are ready for high-temperature compression vulcanization in molds. Neal Jinyu
